In a similar manner, you can use the Excel SUM function to find the cumulative sum for your bank balance. In cell B4, the formula turns into SUM($B$2:B$), and totals numbers in cells B2 to B4, and so on: So, when our Sum formula is copied to B3, it becomes SUM($B$2:B3), and returns the total of values in cells B2 to B3. For more information about Excel cell references, please see Why use dollar sign ($) in Excel formulas. The second reference without the $ sign (B2) is relative and it adjusts based on the relative position of the cell where the formula is copied. Because an absolute reference never changes no matter where the formula moves, it will always refer back to B2.
In your running total formula, the first reference should always be an absolute reference with the $ sign ($B$2). To calculate a running total in Excel, you can use the SUM function combined with a clever use of absolute and relative cells references.įor example, to calculate the cumulative sum for numbers in column B beginning in cell B2, enter the following formula in C2 and then copy it down to other cells:

How to calculate running total (cumulative sum) in Excel How to create an Excel cumulative chart.The following examples show the fastest way to calculate running total in Excel and plot a cumulative graph. This technique is very common in everyday use, for example to calculate the current score in games, show year-to-date or month-to-date sales, or compute your bank balance after each withdrawal and deposit.
It is used to show the summation of data as it grows with time (updated every time a new number is added to the sequence). This short tutorial shows how a usual Excel Sum formula with a clever use of absolute and relative cell references can quickly calculate a running total in your worksheet.Ī running total, or cumulative sum, is a sequence of partial sums of a given data set.
